Petrolatum foot spray offers comfort and convenience to diabetics

For people with diabetics, it is important to protect the skin on their feet and keep it properly moisturized in order to avoid potential issues, such as ulceration. However, hand application of moisturizers on the feet can be uncomfortable, difficult and messy — and so, many diabetics don’t moisturize regularly or often enough. A solution is to use a petrolatum-based barrier spray specifically created for diabetic feet, such as the one by Aurena Laboratories. The spray is manufactured using continuous spray packaging, also known as bag-on-valve. When sprayed on to the feet, there is no need to rub the petrolatum. Broken and chafed skin may therefore be treated without touching the skin surface.

How Does Diabetic Foot Barrier Spray Work?

Using petrolatum as the principle ingredient, the barrier spray reduces water loss from the skin surface, keeping skin smooth and pliable. It creates a barrier that protects intact and irritated skin from damage, reduces friction and soothes sensitive skin.

The diabetic foot product is manufactured in a bag-on-valve spray, so there is no need to rub the petrolatum on to the skin. Broken and chafed skin may therefore be treated without touching the skin surface, potentially reducing pain or discomfort and minimizing the risk for transmitting irritants and/or bacteria.


Bag-on-valve technology allows diabetic foot spray to be sprayed from any angle or position with an emptying rate close to 100%, without loss of velocity and no chilling effect. Product claims include:


  • Improved healing

  • Prevents further skin damage

  • Doesn’t sting on application

  • Preserves skin integrity as an emollient

  • Non-contact application on intact, sore or broken skin

  • Sterile and preservative free, with 3 year shelf life

  •  Stored can in a horizontal position without leakage

  • Can be sprayed with the canister in any position


Comparing the Effectiveness of Diabetic Foot Barrier Spray Versus Hand Application

In a recent study, the diabetic foot barrier spray in bag-on-valve packaging was compared to a hand-applied product of pure petrolatum. The measurement of the spray was based on trans-epidermal water loss (TEWL) when both products were applied to affected areas of volunteer patients. For true comparison, equivalent weights of petrolatum were delivered by spray and by hand application, over a two day pre-test and test period.


Petrolatum products used in the study




Diabetic Foot Barrier Spray (100% dosage)


Diabetic Foot Barrier Spray (50% dosage)


Petrolatum (equivalent to the 100% spray dosage)

Note: Both barrier sprays were manufactured by Aurena Laboratories. The same grade of petrolatum was used in treatments A, B and C.


Product A was applied in a controlled room from a distance of 15cm to one test area on the forearm, and Product B was applied to the other forearm from a distance of 27cm or 30cm, according to pre-test results. Product C, containing a similar quantity of petrolatum to the 100% spray dosage of Product A, was applied to a third test area by a technician’s hand using a finger cot. Skin barrier function was assessed, by measurement of TEWL, 20 minutes after application.

 The Results

It was determined that the diabetic foot barrier spray was able to form a protective film at both 50% and 100% levels, which is equivalent to that formed with petrolatum is applied by hand. Therefore, the moisturising property of a 50% quantity of petrolatum applied by spray was equivalent to that of a 100% quantity applied by spray or hand.


Gone are the days of rubbing thick petrolatum on sore feet. For patients suffering with skin and foot issues due to diabetics, a comfortable and convenient solution exists in barrier spray.
